-wire-coiling looms and for similar purposes,

in which the liability of the wire to become kinked is obviated.

Figure 1, Sheet 1, of the drawings shows a coiling-loom in perspective,or as much of it as is necessary to illustrate my invention; and Figs.-2, 3, and 4, Sheet2,'show sectional por- I tions of the improvement.

Like letters and figures indicate like parts both in the drawings andspecification.

A is the loom-standard; B, the table upon which the coils C areprojected "as formed by the machine. The machine is driven, by a beltupon pulley D, having a friction-pinion; d, which acts upon the innerface of handwheel E, secured upon the shaft of one of the The wire issupplied to the coiling machinery from the stationary forms F, fromwhich it unwinds around the enlarged heads and passes up through tubesG, which are supported loosely in stands G, as shown in Figs. 1, 2, and3 of the drawings of Sheet 2, the upper end of said tube having collarsupon it, as more clearly seen in Fig. 4, leaving the tubes free togyrate, as shown in dotted'lines, at their lower ends around the forms Fas the wire unwinds and 7 is drawn up through the tubes over the groovedrollers H and around rollers I and J to the feed-rollers of the machine.Thus the wire is supplied from these forms F or stationary spoolswithout any rotation of the spools, as has hitherto beenthe practice,and the advantage of thus unwinding the wire is very ma: terial. First,it saves the power required to start often heavily-loaded spools as eachcoil is formed; secondly, .it avoids the momentum acquired by thespools, which causes them to continue to rotate after a coil is"completed,

and thus unwinding the wire and causing it to tangle in the interimbetween the stopping for the last and starting for the next,coil;thirdly, the strain: exerted upon the wire in suddenly starting therotating spools causes it to vary the pitch in coiling, and especiallywhen twowires are run together, as in the machine shown, supplied fromspools oftenof unequal weight, they are very apt to icoilun like and runapart, and frequently to hop outof the web, thus rendering itnecessaryto cut off and waste more or less of the imperfect coils of.wire, whereas the unwinding of the 'wire 'from a stationary form orspool exerts comparatively no resistance upon it and supplies it to thecoiler at a much more even tension, thus causing it to coil much moreperfectly, and consequentlywith much lesswaste of wire; fourthly,thecoiling-loom can be run much faster, because there areno heavy spools tostart and stop, which becomes, more diffi cult as the speed is increasedand ean hardly" be done-successfully at a high rate of speed.

My improvement is, of course, as applicable 'to a machine for coilingone wire at a time as for twoor more wires. I

Having thus describ'ed'my invention, what I claim as new, and Patent, isg In a wire-coiling machine, a stationary form winding wire isconducted, that is so connected at its upper end as to permit .of agyratory movement of the lowerend, and the said lower end adapted tomovein an orbit about the head of the spool, substantially as shown and'described.
